Prefabricated assembly type square culvert with joists and installation process method of prefabricated assembly type square culvert
The invention discloses a prefabricated square culvert with a joist and a mounting process method of the prefabricated square culvert, relates to a prefabricated concrete square culvert with a joist, and further relates to the mounting process method of the prefabricated square culvert. The problems that a prefabricated square culvert is difficult to manufacture, transport and install, the material strength is not fully exerted, and a prestressed tie bar is subjected to fatigue damage after multiple sections of square culverts bear heavy loads for multiple times are solved. The square culvert comprises an upper cross beam, a middle retaining wall, a lower beam, a plurality of culvert body pipe joints, a plurality of prestressed tie bars and a plurality of high-strength bolts. The culvert body structure further comprises two joists, the two joists are attached to the lower surfaces of the culvert body pipe joints side by side, and the two ends of each joist are installed in the grooves reserved in the two lower beams respectively. The installation process method comprises the steps of prefabricated part position installation, bolt connection, prestress setting and the like. The wall thickness of the culvert body pipe joint of the prefabricated square culvert is reduced, so that the problem that the square culvert is difficult to manufacture, transport and install is solved; when a load is borne, the joists and the prestressed tie bars are stressed together.
一种带托梁的预制装配式方涵及其安装工艺方法，本发明涉及一种带托梁的预制装配式混凝土方涵，还涉及装配式方涵的安装工艺方法。它解决预制装配式方涵制作、运输与安装困难，材料强度发挥不充分及多节方涵在承受多次重载后预应力拉筋疲劳破坏的问题。方涵包括上横梁、中间挡墙、下梁、多节涵身管节、多根预应力拉筋和多个高强度螺栓；它还包括两个托梁，两个托梁并排贴合在多节涵身管节的下表面上，托梁的两端端部分别安装在两个下梁预留的凹槽中。安装工艺方法包括预制件的位置安装、螺栓连接和预应力设置等步骤。本发明缩小预制装配式方涵的涵身管节的壁厚，以解决方涵制作、运输与安装困难；承受荷载时，托梁与预应力拉筋共同受力。
